Best way to implement a 'clock'

I've done this in vb6 - but wanted to know the best route to take in vb.net (2005).
I simply want a label with the current time HH:MM:SS to update every second.

If a timer is the best route, can someone assist me in writing the code for it - without placing the timer control on the form?

Go ahead and PLACE the timer control "on the form" - it is not visible, so it won't cause you any problem - it is just a way to indicate to the designer that you are using it!

you don't need the timer as a component. Have a look to this article about using the .net Timer() class:

A simple VB.Net version...
Public Class Form1
 
    Private WithEvents tmr As New System.Windows.Forms.Timer()
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        tmr.Interval = 1000
        tmr.Start()
    End Sub
 
    Private Sub tmr_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles tmr.Tick
        Label1.Text = DateTime.Now.ToString("hh:mm:ss")
    End Sub
 
End Class

*Note that in VB.Net you can use the WithEvents/Handles combination...    (C# doesn't have a direct equivalent)

Thanx IM - that's what I'd been trying to get working, but was missing something...
I think at one point it was complaining about tmr already existing in 'this' class, although I couldn't find any reference.
Will give this another shot - thanx!
